and also showing the windshield and canopy The cockpit may be'provided With suitable r top. The cabin extens on 1s shown in dotted sitting accommodations in the usual manner. 50 lines, in the raised positlo Preferably thesteeringwheel 17 and other application #561,101, maybe employed if desired or the motor propeller maybe used for steering in any well'known manner.

Thecabin accommodations may ofcourse be arranged to suitindividual desireswithin the limits of the available space. It is highly desirable, however, to provide a pair-of berths such as 20, one on each side and these may be hinged as at 21'along their'outer'edges' so asto permit-them to be swung upagainst the sides of the boatleaving the cabin floor clear. The ends of the berths extend forwardbeneath thedeck 13 and the cabin extension 14' so as to leave space at the rear end of the cabin for a stove 22 and a. sink 23-.and the usual ice-box andcupboa rd or locker accommodations.

The additional head room is provided by forming'the central-part 25 separate from the rest of .the roof and mounting, it in sucha manner that it maybe raised conveniently so,

as to provide convenient space atleast. over the rear end and the central portion of the cabin so as to facilitate: work around the sink or stove and movement longitudinally between the berths, and to provide free space in the center whenthe berths are swung back out of the way. This central roof. section is normally supported in a suitable manner, for instance, on the side timbers 26,and may be provided with weather strip closures 27 'covering the joints. End supportingblocks suchas 26, may be employed. i i The sides of the cabinextension in'the form shown consist of two longitudinal sections 28 and29. The lower section 28 is hinged at 30 to the timber or beam 26 extending longitudinally ofthe boat. The section 29 is hinged at 31 to a longitudinal timber 32 forming a part of theextension roof structure- The two sections 28 and 29; are hinged together along the line33. These three hinges may conveniently be what. is commonly termed a piano type hinge. WVhen the extension roof is down the side sections may be conveniently sus{ pended, for instance, by a number of'hooks 34. I To secure the additionalhead room it is merely necessary to lift the roof section 25 whereupon the side sections 29 and 28 swingintoplace and may be held in elevated position inany suitable manner, as for instance,

by means of bolts 35 or other suitable latch mechanism. These side sections 28 and. 29,

maybe provided with windows orventilating passages in any well known manner.

Each end; of the roof extension may be closed in any suitable manner, as, for instance, by means of an end piece 36 hinged at'37. WVhentheeXtension is down this end piece 86 will lie between the sections 29 and'the roof. lVhen the extension is up this end piece-36 will be lowered into place and will serve to hold the sides in the upright position the lower edge of 36 may be then supported by block 26. The extension when raised and thefront' end down, may be held by any'suitable bolt or latch 38. The aft end of the extension may be closed by means of a member 40 which in the preferred construction may constitute a windshield supportedby the canopy top 41.

This canopy top 41 may be supported by frame members 42 and posts 43.

I also prefer to provide the windshield sections 44 on each side of the-central shield 40 and allfof these windshieldsections may be supported in any'convenient manner. The section 40, however, is preferably hinged at 45 at the top so that it can be swung upwardly and to the rear leaving greater head room for entranceto the cabin whenthe extension roof 1s up.

.Preferablythis windshield arrangement is a. short distance 'forwardof the walls 15 and doors 16 so thata ledge '46 is provided on each side of the. cabin convenient for the helmsman to deposit maps, instruments, etc.

These ledges 46 constitute parts of the roof of sections50 extending between the canopy top and the roof ofthe cabin.

It will be obvious from the foregoing that the doors 16 maybe opened for entrance-to the cabin atany time. The. various doors may bemounted to slide instead of swing wherethere is suitable space for such sliding action. 1

i The hatches 47 canbe raised at any time for ventilation which is especially desirable immediately above the. stove22. When the roof extension is raised its rear edge inter:

locks beneath the front edge of the canopy top 41. By raising the hatches 47 and the windshield 40 full head room is provided from the cockpit into the cabin.

When the extension roof is'up it .will be obvious that it may be closed at the rear by the windshield 40 but that it does not obstruct the vision of the helmsman through the windshield sections 44 at each side.

When the extension roof is down in what might be termed the normal. cruising position i there is still head room enough in the cabin to permit its use in the customary manner since none of the parts involved in the extension construction provide any substantial obstruction.

boat and a horizontal propeller driving in 7 It should be understood that the construction and arrangement may be modified in dotail within my invention, for instance in Figs. 6 and 7 I have shown the construction :in

which the windshield section is normally section 25 so as to permit the center roof section to be raised. The windshield section can then be slid back into the dotted position shown in Fig. 6 serving as closure for the extension. In this case the sides 58 of the cabin are extended rearwardly to obtain extra space in the cabin in rear of the doors. Such a construction may be desirable when an inboard motor is usedin which case the extra space in the center of the cockpit is more important than in the cabin.

In Fig. 9 I have shown an inboard motor with reverse gear 56 and the propeller 57.

is carried by a shaft housing 58 and plate 59 which is mounted in an opening in the casing 60. The housing 58 may be hinged at 61 to permit retraction of the propeller into the casing. The plate 59 may be suit ably held down to close the opening in the bottom of the casing. The propeller is driven by the motor through suitable clutch andgear trains which'permit the propeller to be retracted for inspection, repair, etc. This arrangement affords excellent balance in the solid water beneath the plate, at the same time obviating inaccessability and stuffing box leakage commonly encountered when inboard type motors are used. The propeller thus mounted can tilt to clear bottom obstructions and permits replacing shear pins. removing weeds, oiling, etc. with ease and safety from inside the boat while afloat.

The motor being set level on the main framework aft the longitudinal center of the boat is in the best position to insure stability, easy running and properly distributed load, there being no driving strain 011 the transom and no long inclined shaft through 4 the boat bottom.
